2U barebone for AMD EPYC 8004
This 2U rackmount barebone accepts a single AMD EPYC 8004 series processor in an SP6 socket. It provides twelve hot-swap 3.5" SATA bays and two hot-swap 2.5" SATA bays for high-density storage. Eight DDR5 4800 DIMM slots support up to 96 GB of memory. The platform targets general-purpose server workloads needing local capacity.
Redundant 800 W CRPS under continuous demand
Dual 800 W CRPS units rated 80-PLUS Platinum/Titanium share the load, so sustained operation does not rely on a single supply. Fan tachometer monitoring and multi-speed control adjust airflow automatically as CPU temperature rises. The chassis operates between 10 °C and 35 °C, allowing steady performance in typical data-centre aisles without thermal throttling.
Tool-less drive carriers and front I/O access
Twelve 3.5" and two 2.5" trays slide in from the front, letting technicians swap drives without rails or screws. Two HHHL PCIe 5.0 x16 slots and two M.2 PCIe 5.0 x4 connectors sit inside for add-in cards. Rear connectivity includes dual 1 GbE RJ45 ports, two USB 3.2 Gen 1 Type-A ports and a VGA output driven by the Aspeed AST2600 controller.

Questions about this item
How loud and hot does the 2U12L2S-SIENA get when the dual 800 W CRPS supplies run continuously?
The chassis uses quiet fan control that auto-adjusts speed by CPU temperature, and the 1+1 800 W CRPS units are 80-PLUS Platinum/Titanium rated for high efficiency. Operating temperature range is 10 °C to 35 °C.
Which CPU, memory and drives must I supply to make this barebone operational?
You need one AMD EPYC 8004 series processor for the SP6 socket, up to 96 GB of DDR5 4800 RDIMM across eight 288-pin slots, and 3.5" SATA drives for the twelve hot-swap bays plus optional 2.5" SATA drives for the two 7 mm bays.
Will my existing PCIe 4.0 add-in cards work in the two HHHL PCIe 5.0 x16 slots?
Yes, the two half-height half-length PCIe 5.0 x16 slots are backward compatible with PCIe 4.0 and 3.0 cards, so older expansion cards will function at their native speeds.
